Thirteen less than twice a number is fifteen. What is the equation? What is the number?
Hi there!
Let the unknown number be c.
Twice a number means we multiply that number by 2:
2c
Now, subtract 13:
2c-13
This expression is equal to 15:
2c-13=15
As soon as I added the equal sign, and the number than the expression is equal to, the expression turned into an equation.
Now, let's solve it for c.
2c=15+13
2c=28
c=14
Hope everything is clear :-)

Answer:
I am assuming that you are talking about problem 2. so I will answer that.
Step-by-step explanation:
-2x + 6 ≥ 3x - 34
+2x +2x
6 ≥ 5x - 34
+34 + 34
40 ≥ 5x
÷5 ÷5
8 ≥ x
So, x can be anything equal to or less than 8.
Answer:
x≤8
For the graph closed circle on 8 with the shading going to to left
Step-by-step explanation:
-2x+6≥3x-34 (given)
Subtract 6 on both sides
-2x≥3x-40
Subtract 3x on both sides
-5x≥-40
Divide by -5 on both sides
x≤8
*The sign flips because you divided by a negative (-5x)

What is ratio ?Ratios are required form comparing two or more quantities which are of same type.
a/b can be written in ratio form a:b.
According to the given question
A candy store makes a 12-lb mixture of gummy bears, jelly beans, and gobstoppers.
The mixture calls for three times as many gummy bears as jelly beans.
∴ If the mixture has 1 lb of jelly beans then it will also hence 3 lbs of gummy bears.
By going through options we can observe option B is satisfying this condition as 6 lbs of gummy bears is 3 times 2 lbs of jelly beans and the rest are gobstoppers which is 4 pounds.
For more assurance to our given choice we can check with the price of individual contents too.
Total mixture is 24 dollars and gummy bears, jelly beans and gobstoppers costs 2 dollars, 3 dollars and 1.5 dollars respectively.
∴ 6(2) + 2(3) + 4(1.5)
= 12 + 6 + 6
= 24 dollars.

(6a-3)=(7b-10)
Answer:
for A=[tex]\frac{7b-7}{6}[/tex] and for B=[tex]\frac{6a+7}{7}[/tex]
Step-by-step explanation:
For A
[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]
[tex]6a-3+3=7b-10+3[/tex]
[tex]6a=7b-7[/tex]
[tex]\frac{6a}{6}=\frac{7b}{6}-\frac{7}{6}[/tex]
[tex]a=\frac{7b-7}{6}[/tex]
For B
[tex]\left(6a-3\right)=\left(7b-10\right)[/tex]
[tex]7b-10=\left(6a-3\right)[/tex]
[tex]7b-10=6a-3[/tex]
[tex]7b-10+10=6a-3+10[/tex]
[tex]7b=6a+7[/tex]
[tex]\frac{7b}{7}=\frac{6a}{7}+\frac{7}{7}[/tex]

1) On a road map, the distance from Louisville to St. Louis is 12 cm. If the map has
a scale of 2 cm = 20 miles, what is the distance to St. Louis?
120 miles.
All you have to do to understand this problem is the relationship between the cm and mi.
In this case:
2cm =20mi.
The relationship is times 10, because 2 x 10=20
So multiply 12 by 10, and you will get 120mi.
Therefore, the answer is 120mi.

The formula A=lw gives the
area A of a rectangle with
length 1. What is the area in
square feet of a rug with a
length of 13 feet and width of
6 feet?
Answer:
78 ft^2
Step-by-step explanation:
A = lw
l = 13 ft
w = 6 ft
A = 13ft x 6 ft
A = 78 ft^2
Multiply the length by width to find Area. The unit for Area will be feet squared because both the numbers for length and width had the same unit.
